Kapu Blockchain Explorer

Ark Explorer version 0.2.0 works in conjunction with the Ark Core API. It uses Redis for caching data and Freegeoip to parse IP geo-location data.

Build Status

Prerequisites

These programs and resources are required to install and run Ark Explorer

  • Nodejs v6.9.2 or higher (https://nodejs.org/) -- Nodejs serves as the underlying engine for code execution.

    curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
    sudo apt-get install -y nodejs
    
  • Redis (http://redis.io) -- Redis is used for caching parsed exchange data.

    sudo apt-get install -y redis-server

  • Freegeoip (https://github.com/fiorix/freegeoip) -- Freegeoip is used by the Network Monitor for IP address geo-location.

    wget https://github.com/fiorix/freegeoip/releases/download/v3.1.5/freegeoip-3.1.5-linux-amd64.tar.gz
    tar -zxf freegeoip-3.1.5-linux-amd64.tar.gz
    ln -s freegeoip-3.1.5-linux-amd64 freegeoip
    nohup ./freegeoip/freegeoip > ./freegeoip/freegeoip.log 2>&1 &
    
  • Bower (http://bower.io/) -- Bower helps to install required JavaScript dependencies.

    sudo npm install -g bower

  • Grunt.js (http://gruntjs.com/) -- Grunt is used to compile the frontend code and serves other functions.

    sudo npm install -g grunt

  • Forever (https://github.com/foreverjs/forever) -- Forever manages the node processes for Ark Explorer

    sudo npm install -g forever

  • Git (https://github.com/git/git) -- Used for cloning and updating Ark Explorer

    sudo apt-get install -y git

  • Tool chain components -- Used for compiling dependencies

    sudo apt-get install -y python build-essential automake autoconf libtool

Installation Steps

Clone the Ark Explorer Repository:

git clone https://github.com/kapucoin/kapu-explorer.git
cd kapu-explorer
npm install
bower install

Build Steps

Frontend

The frontend must be built with Grunt before starting Ark Explorer. Run the following command to compile the frontend components:

grunt compile

Market Watcher

Candlestick data needs to be initialized prior to starting Ark Explorer. During runtime candlestick data is updated automatically.

To build candlestick data for each exchange run:

grunt candles:build

To update candlestick data manually run after initialization:

grunt candles:update

Configuration

The default config.js file contains all of the configuration settings for Ark Explorer. These options can be modified according to comments included in configuration file.

Top Accounts

To enable Top Accounts functionality, start your ark node (not the explorer) using the following command:

{
    "port": 4600,
    "address": "0.0.0.0",
    "version": "0.1.0",
    "fileLogLevel": "info",
    "logFileName": "logs/kapu.log",
    "consoleLogLevel": "info",
    "trustProxy": false,
    "topAccounts": false, <--- This line needs to be changed to read true

Managing Kapu Explorer

To test that Kapu Explorer is configured correctly, run the following command:

node app.js

Open: http://localhost:6040, or if its running on a remote system, switch localhost for the external IP Address of the machine.

Once the process is verified as running correctly, CTRL+C and start the process with forever. This will fork the process into the background and automatically recover the process if it fails.

forever start app.js

After the process is started its runtime status and log location can be found by issuing this statement:

forever list

To stop Explorer after it has been started with forever, issue the following command:

forever stop app.js

Tests

Before running any tests, please ensure Kapu Explorer and Kapu Client are configured to run on the Ark Testnet.

Replace config.js with config.test file from the test directory:

cp test/config.test ./config.js

Replace the config.json for the Ark Client the corresponding file under the test directory:

cp test/config_Ark.json /PATH_TO_Kapu_DIR/config.json

Then restart the Kapu Client (example):

bash /PATH_TO_Kapu_DIR/Ark.sh reload

Launch Kapu Explorer (runs on port 6040):

forever start app.js

Run the test suite:

npm test

Run individual tests:

npm test -- test/api/accounts.js
npm test -- test/api/transactions.js
